I’ve been using SmartThings for the last couple years (v2 hub, SmartThings Classic software), happily for the most part. I’ve got a number of automations setup, all which have been working flawlessly until a week ago. Automatons based on a sunrise/sunset trigger stopped working entirely. I did get those working again, but only using a fixed time for the trigger.
However, it isn’t just sunrise/set triggers that suddenly stopped working (or working reliably). I have a switch that triggers a scene, which stopped working entirely, while other switch-triggered scenes work fine. This morning, my Good Morning automation didn’t run, which had been working fine until today. If I trigger any of these scenes/automations manually, they work every time. Looking at the logs, SmartThings just isn’t running the automations when it should; when they don’t work, there is no entry that it even tried.
Most everything still works, but it’s frustrating to go from completely reliable to much less so, without any other changes on my end. I’ve not been able to pin things down to one specific thing.
I’ve emailed support a couple days ago (no response yet) after exhausting all my ideas on how to fix. I’d like to check with you all and see if anyone else has run into this lately, or has any solutions.
